"Field & Stream", "Outdoor Life", and "Sports Afield" always have articles about how to find where deer are likely to be during the hunting season. There will be articles covering the "how to" for different parts of the U.S.
Your best bet is to find a gun store or barber shop with some back issues. Usually, the articles start showing up in the issues which hit the news stands in August and September.
Not having any idea of where you are hunting, there is little specific info I could offer. In general, however, try to find a "hidey-spot" some 20 to 50 yards away from (and best if you're elevated somewhat) any place where you find a buck's scrape on the ground. It will be a place where he has pawed the ground and urinated. The problem is that he might only come back every couple of days, and possibly at night.
Deer are edge animals. They rarely wander out into broad open areas, unless the grass is pretty high--near shoulder height, anyway. They will often come out in late evening into open fields, and leave around daylight--which is why guys build stands in trees along such an edge. But you watch the field less than you look along the edge of the tree line. Powerline edges are also good places--look for deer trails crossing them.
If there is a lot of hunting pressure, "real" bucks are gonna lay up in some thick-brush hidey-hole near food and water, and not move during daylight. Oh, they'll get up and pee, sniff around a bit, and then bed down again. Places like that are best looked for well before the season opens, or at least a couple of weeks or so after the season closes. You don't want to unduly "educate" him.
Deer generally feed downwind. That way, they can smell any Bad Thing behind them, and see in front. If spooked, they tend to run back toward where they came from--they know it's safe, there. (Same on a highway, at night. Never try to cut behind a deer in front of your car. Cows, however, are just the opposite. So, go in front of deer; behind cows. Horses are suicidal; they try to stay in front of you, no matter what you do.)
When startled, larger bucks almost always run uphill and upwind, looking for a saddle in a ridge. Or, they'll bed down near a saddle, on the downwind military crest. Does and little bucks will go any old direction; and, as I said, mostly upwind--but not always. (There ain't no "always" with deer.)
If you jump some does, and there are few if any fawns/yearlings, don't watch the does. Look the other way; the buck won't stay with the does. If the does all have fawns/yearlings with them, the odds are that there is no buck around...
"Mostly"; "generally". There ain't no "always".
Hope this helps,
