Lived off of elk and venison (and a wild boar) for two years while in grad school.
Easiest, yet delicious, was to marinate venison steaks. You can pan fry, broil or roast on a grill while camping. Marinades should be 1/3 vinegar. 1/3 oil & 1/3 water. Place in a plastic bag and refrigerate. Bottled salad dressing (Italian, Balsamic, etc.) works well (marinate 6-18 hours--24 hours makes it too strong). Or make your own with garlic and/or other herbs, remembering an acid and an oil.
Secondly (a little more complicated), slice venison thin. Place in a bowl or large baggie. Add Gebhardt's chili powder (1 tablespoon/lb.), 1 tsp garlic, Mexican oregano, cumin, ground coriander. If you have it, achiote and adobo spices. Chipotle will make it spicier; reduce chili powder for less spicy. I adjust by smell. Mix well; if using a bowl. place mix in baggie or just cover well. Marinate over night. Place a couple of tbls. oil in a wok, fry meat as desired, add sliced onions, poblano or bell peppers (colored peppers don't add to flavor but improves) and fry until soft but not "mushy". Tomatoes optional. Serve with cheese, guacamole & hot sauce on warm corn tortillas.
