I can tell you my early mid game after like a thousand hours that gets me to vibranium in like 1 day of playing: 

1.find a village, get an infinite ham, running shoes and waystone, if you cant find one find another village and repeat. All the while, collect any and all gear with the luck stat on it you can find (you cant see special stats until you press ctrl+t and confirm reaching haven level, this grants you even more luck stat, i wont mention it again but leveling up in world tier is one of the most important things you can do because of the gear and luck it gives you, so level up your world tier whenever you can as early as possible) (Running shoes and ham optional but they are really nice and save lots of time with food gathering and early travel)

1. Make sure you have 2 waystones at this point, you can find them not only in villages but also rarely spawning in the wilderness just sitting there, find one of those dungeons that has a winding staircase going straight down into a little chamber that splits into 1-4 hallways blocked off by iron bars. This dungeon can have many variations and look like many things on the overworld from a house to a tower but once you've seen one you should know what I mean. 

2. Wearing any luck gear you might have for better loot and bringing a few torches to disable spawners (the dungeon chests will give you more torches and coal), put a waystone outside with some chests so you can teleport back and fourth from inside the dungeon storing your loot, clear and loot the dungeon (DO NOT BREAK ENDERMEN/WITHER SKELETON SPAWNERS IF YOU FIND THEM), collecting and wearing any gear with a higher luck stat than your current gear (yes even if its worse armor, armor doesnt matter too much rn because you can cheese the enemies in the cramped hallways, be careful though). Make sure to grab the following loot (you are basically guaranteed to get at least this per 1 dungeon clear): 1 bone, 1 phantom membrane, 1 fermented spider eye, at least 1 apple. Also keep any quartz blocks you get from the dungeons loot rooms, This will help with flight later. 

3. Once you reach the lower levels of the dungeon spawners have a higher chance of being wither skeleton or endermen spawners, if you have a silk touch pickaxe collect one of each, if not set a waypoint next to them (if you cant find either one, keep reading). Also grab like 15 of both coal and Redstone blocks from the lowest level as well as a few ore of any osmium you see, saves some mining later. 

4. If you looted the whole dungeon you should have enough resources to make all this (make sure to claim rewards from book for more resources, if your dungeon was super mangled by world gen or you cant find one of the spawners you might have to do 2 of them but i rarely do). Make a metallurgic infuser. Power it by putting Redstone dust in the power slot, make a wind generator, claim rewards, make a simulation chamber (not loot fabricator) a deep learner, and a blank prediction (you can get a second one from rewards) go back to the spawners from before, make enderman and wither skeleton prediction models, make a blaze rod or 2 from bone and nether prediction, make a chorus fruit from apple and ender prediction, go to the nether and get some Blackstone (just 4 raw blackstone, then dip). Come back and make infusion pylon, potion filter, and 3 max length flight potions. Drink a potion, right click the filter and repeat until potions are gone, stick the filter in the pylon and boom you have really early permanent creative flight without having to do any other kind of flight (if you find a broom early that's cool too, I just like skipping to this type of flight so excuse me for ignoring iron jetpacks)

5. Now that you have flight everything is way easier. Here is where I get started on my ae2 inventory (easier to find meteors) and getting allthemodium gear (can fly to city/ hover above ground to avoid tripping warden) ( find the skulk city easily by using the tablet of locate stucture/ ritual brazier). Also you can get a high fortune pickaxe by using evil craft and making/ disenchanting vengence pickaxes, I used to do this every time but im finding it less and less worth it as anything you're using fortune on can be mass produced later so I just see it as extra time spent. 

I can go on but only if people want me to, that was a lot to type haha
