If you're going to use military packs for hauling meat, make sure to buy some of the large size 6mil poly bags from u-line lest your gear be covered in blood.
I tend to do a somewhat typical "car hunt". Usually spend the first bit of time driving around with the spotting scope mounted to the door. I drive up onto a ridge and then spend an hour or two scoping things out (usually looking for sign), then displace, and do the same thing. If I see an especially promising spot, I may dismount and go check it out. Usually hunting is a vacation that ends once I kill an animal, so I am never anxious to make a kill.
What I consider necessary to have with you no matter what:
1) A zeroed hunting implement - This is key, only hits count, and only fast clean kills count as hits. Spending time looking for a wounded animal is no fun.
2) Gutting/Butchering tools - Generally this is a knife and a saw. Big animals may need to be cut up before being moved. I've found those oversized survival knives work well as a saw (the back of the blade often has a saw), but are a poor substitute for a good knife. My butchering kit is: Pair of EMT Shears, Box cutter, folding pruning saw, and a skinning knife. Typically a skinning knife has a short wide blade with a small rounded handle so you can run your index finger along the back of the blade. My preference is for carbon steel, also be sure to have a sharpening stone, if you're not cutting you're sharpening. I usually also have some shoulder length disposable gutting gloves, and a set of heavy duty nitrile gloves that I can wear over those and a trash bag.
3) Drag harness, Litter, Rope - Most of these are pretty obvious, for the litter, I have a sheet of HDPE that's 24" wide, and 5' long, I put grommets around the edges every 6 inches, so you put the animal on this, run the rope through the grommets and tie to the harness. It's an easy way to drag the animal out, and keeps it from getting too torn up.
Personal stuff:
Camera - make sure it's got fresh batteries, I dunno why but everytime I make a big kill, the batteries are always dead.
Radio - We usually hunt in packs, radio allows us to span a greater area, and if there are multiple animals we can coordinate. Generally, we usually use this as a safety measure, if you got something in your sights, might want to check where your buddy's are before accidentally shooting one of them.
Water - You need something to drink while you're doing all that walking.
Food - I like trailmix or jerky. Salty food always makes me drink water and stay hydrated.
IFAK - usually just bandaids, a compression bandage, some ibuprofen.
Spotting scope or binoculars - maybe a tripod. I spend a lot of time glassing.
GPS - Again, fresh batteries. I like to record the places I make kills, and also record places where sign is heavy.
Tarp or poncho - I can construct a hide, or more often I use it to put up as shade. I typically hunt coyote and pig, coyotes pick you out by noise, pigs pick you out by smell. Generally, the coyotes will bolt if they hear a vehicle coming, even if you speak too loudly. However if you're sitting up there on a hill they usually care less until you start shooting at them. Pigs start to get pretty excited when the bullets start to fly, but if you're more than 100 yards away or so, they don't know you're there.
I usually try to keep my carry kit as small as possible, back at camp you're going to need a gambrel and more rope to tie up your quarry and start butchering, usually I want running water to wash the meat and tools off, this also helps remove any residual body heat, and helps prepare it for going in the cooler.
