Well, aside from you gun and ammo, I'd suggest you bring the following:

raingear
binoculars
food
water
game bags
knive and knife sharpener
flashlight
game harness(for dragging your deer out)
sunscreen
hat
survival pack(with first aid kit)


Hope this helps! Its just the basic stuff that i take on hunting trips, so you might want to add anything else you can think of that you might use.

Good luck hunting!
