Get a small metal cup, a soda can stove and some HEET or denatured alcohol. Get a camelbak or two one litre bottles, some tabs and a filter. Get a sleeping bag, tent or bivvy, ground pad, rain fly if you need one, and rain gear. Carry a few hand warmers just in case. I keep a lighter on me, in my mess kit and in my first aid kit. I carry a folding knife on me. The only other thing you'll need is food. I always carry two days' worth of extra food (extremely calorie dense) in addition to my typical dehydrated camping food (mountain house). I don't carry axes or saws or kukris or shovels. Buy yourself a military field guide and a local plant identification field guide memorize them, then carry them anyway. You can always add to this later, but most people make the mistake of buying a thousand things they never use, watch "wild", you'll see what I mean. I have several decades worth of pointless gear I've collected, myself. It took a long time and a lot of trips before I realized how little stuff I really needed.
If you'd like to go the bivvy route, I'm working on a group buy to get some cheap. Check it out:
