The particular pack I use varies. Smallest/lightest pack wins if it can carry the stuff I need. In MI we're often hunting 60* days in early Oct and 30* days Nov 1 so...
Shooting stuff gear (bow, xbow, rifle, pistol, shotgun, whatever)
Climbing stuff gear (saddle, tether, platform, sticks, whatever)
Deer foolin' gear (decoy, other misc foolishness)
Tree hanging strap such as

but not that one, something like it.
Doyles gear hoist (self-retracting heavy thing is preferred for not having to tidy ropes manually)
Binoculars and sometimes FLIR Scout for S&Gs
Food/snacks if sitting for a long time
Hydration
Staying warm gear (probably not worn on hike in)
TP
BooBoo kit with bandaids and pain relievers
Hand warmers
Orange tape (if I need to mark trail to downed critter)
Tags/paperwork
At least 2 flashlights, usually 1 is handsfree headlamp with red light
Compass
9mm (because you can never be too safe)
