You should set ALT to 80km, ANT to between 40 and 50 (depending on how fast you want to descend) and ANG to between 0.7 and 1
that gives you a deorbit almost exactly on the far side of earth, once you hit the atmosphere, check your attitude AP is holding AoA NOT pitch )theres a button on the top right of that panel)
aim to hold a descent speed, not your AoA, that should change throughout the descent, starting from 42-45 and ending about 30 (read on)
holding 80m/s is my usual target, but you can go higher without burning up, and lower to extend your re-entry (but dont go too low, or youll lose too much speed and then burn up after a kinda secondary stall)
once your speed gets below 2.3k, you can roll out of the high AoA, and use aerobrake mfd to set your traget impact point about 100k ahead of your target (1/2 to 2/3 of a square on the zoomed map)
then you should pass a few kms over your target, just descend like a glider (in a descent spiral a couple of km after the end of your target runway, and move in for landing when you can descend to it without losing control
if you find yourself way too short (we've all done it, dont worry) you can open your scram doors if you have any fuel left, or use your mains, prefferably early on in the higher atmosphere where they have a greater ISP, but save some for your final approach if you need it
