Simple, just hunt the down wind side of where you expect the deer to be, or becoming from.
It pretty much is that simple IMO. Everyone has stands where deer can come from every direction. You can't be 100% "windproof" from such stands. Simply put hunt the wind according to where the deer predominately come from. Other stands are more clearcut with hunting wind direction. The ones where deer come from a certain direction 95% of the time. Setup where the wind will be blowing away from that. I pay particular attention to bedding areas. At all costs I try not to let my scent blow into where I know they are bedding. The key is to identify where they bed, eat and how they get there (most of the time). Then just setup accordingly and don't hunt an area unless you know your scent is not going to be blowing in those directions. Go back to keeping it simple. Deer will come from this direction most of the time, dont' have my scent blowing there.
good thread by the way. I'd like to hear some different guys setups according to the wind. I think we can all learn from it.
One example for me....
I have a stand 50 yards inside the woods just off a corn field. In front of me is the corn, behind me is thickets/hardwoods where I knowdeer bed. They come from the bedding area in the PM to the food source. Knowing they bed and travel towards the corn in the PM I'm not sitting there if the wind is blowing behind me. I'd prefer to have the wind blowing out to the corn(or sideways works too)for this particular stand. Can "some" deer come from the corn and head towards this bedding area? Sure... and it happens. And I usually get winded [8D]. But predominately it's going to happen just the opposite and that's what I'll setup for.
