Wow, where to start? How long of a hike, what kind of terrain, what weather do you expect, and what about a water source near your camp site? A starting list (with some obvious stuff in it...):
Light free-standing tent, tent ground cloth, tarp (light one, like Noah's Tarp), one 6' tarp pole, about 2x20ft of paracord, 3ft duct tape wrapped around one of your water bottles, a water purifier (pump type), wool socks, non-cotton clothes, matches, dryer lint (for starting fires), baggies (for keeping things like tinder, matches and electronics dry), a backpack w/rain cover, sleeping pad, down sleeping bag (keep it in a garbage bag in case of rain), clothing layers, bug spray, hat, sunscreen, walking stick, first aid kit, mole skin (or use duct tape), Mountain House food, coffee/tea, portable stove w/small pot/cup that comes with it, spork, fuel, 4L water (depending on water source, etc.), power bars, rain gear (pants, coat, boots), water-proofed paper map, compass, GPS (not your phone), whistle, signaling mirror.
I'm sure I have missed something, but that is a quick list. And don't skimp on equipment. Junky, cheap equipment will just need to be replaced wit better stuff sooner rather than later.
