Whole books on this transition. Look up the basics of ICM and the ranges for shorter stacks. Not being dismissive, its just a broad subject. Long story short, there's far more pressure to chip up and play aggressively, while also valuing survival over small amounts of EV. It can change how you're "supposed" to play in situations. Preflop raises become smaller but I 3-bet more, and with a short stack there's less room to profitably chase draws, gaining less when it hits. Play fast, and concern yourself with your stack size relative to everyone else's; if you fold the next 15 hands, do you get into the money? Big payjump? Is the other mook playing scared, too concerned with the money and nursing 8 BB?
Biggest difference for me was the short stack play. With deepstack, sure, 5BB call is fine for a big draw, but when you're sitting on 22 big blinds that's a huge portion of your stack. I think you'll be surprised how wide you're supposed to be shoving.
