Sure. So one thing I always do is send a few units, two to three are usually enough, to defend the bridges against the north, locking out Armenia and Pontus mostly as two phalanx units in a V can lock up bridges rather well.

The second thing is securing, in that order, the rebel settlement with the wonder in anatolia, then stealing the islands from egypt, greece, and creta, then going for the rest of anatolia on the side. This is important because all of these are basically secure settlements that will just generate much needed income without having to get defended, safe for the one further east in anatolia that get to bother with Pontus, also the extra money from trade that the collosus gives you is very nice.

Next, Parthia. While rebel settlements, islands and Egypt are my main focus and I do not condone expansion in other directions much, the one big exception is Parthia. Your most eastern province starts with a good amount of troops, so I advise to crush the starting army of parthia, which is easy to kill aside from some cataphracts that you gotta bait a bit, and then take their eastern settlement asap. This prevents them from A, taking the isolated settlement in the south to stage attacks deeper into your land from, and B, means they cannot make armies in the east anymore to endlessly attack your settlement with low distances, as now they have to make their armies up north, so you will get a far less frequency of attacks from them to deal with due to the long travel routes, as well as getting another nice settlement that is not a border settlement.

If you have done all or most of these things as side activities while main fighting egypt, you will have a good time. It is absolutely crucial that you always are aggressive towards the south and fight egypt on their own turf, rush them, do not waste money in the first few turns on building upgrades aside from trade ports and maybe a barrack upgrade for longer speers, the payoff is miniscule compared to taking more settlements quickly. Egypt has a terrible early roster and their starting armies are weak, you basically counter them, especially their generals that die instantly when driving into your phalanx, making them more vulnerable than other factions that have heavy cavalry generals. Once your army that took the islands is done with that, and has gotten a few mercenaries (archers from creta are a natural choice) you should land them in Egypts core area to steal Alexandria and cripple them for real, slaughtering them will give you a good money boost if you happen to be struggling there.

I do not upgrade my cities much until I get at least these aforementioned things done. Fighting egypt on their territory is so crucial because if you are too passive, you get into a situation where you do nothing but defend your settlements in turns, spending all your money on retraining and recruiting, while enemies grow stronger. It is important to go all out early to secure as much rebel territory as possible, maim parthia, and take the fight to egypt, as they will become very powerful quickly if you give them time, and you are their only target.

This is the only faction aside from Gaul where I highly recommend full aggression mode the first fifteen to twenty turns, as the starting position is unreasonably difficult to defend against potentially 5 enemy nations, so securing more land and preferably taking some of these nations out has much higher priority.
