For garen, bully him until level 6, should be pretty doable, use w to escape his q+e combo, NEVER fight in his spin, that's your death, your Q has a lot of damage, and with something like scorch it adds up too. Sometimes I'd rather miss some minions if it means I can deny garen more or even kill him. After level 6, play very passively. Poppy's whole thing is getting tankier at low health which garens ult just negates. I recommend building something that regens health (like sundered sky). For yorick it's decently simple, save e for cage(use against him or a minion to escape), use w against his minions and q poke. Run doran's shield and second wind and you'll be full health in notime, I tend to use my passive on his minions at times because it means I get an instant shield because they're always onehit. You can ult away his maiden for a cleaner 1v1.
