First of all take a shower before going out. If possible by some special soap from a sporting goods store and wash with that. They sell a liquid form that you can use for your hair and body. Otherwise don't use soap, but use really hot water. If all else fails use Baking Soda.
Next is make sure you wash all your clothes in baking soda. All your camo and long underwear. You can also buy stuff from a sporting goods store for this, but again Baking Soda works.
Next is make sure you keep your clothes in a Plastic bag when not wearing them.Throw some oak leaves in with them for the woods smell. Pine needles if you hunnt in pines. A Rubbermaid container also works really well, but you have to tape up the vent holes underneath the handles. Don't pump gas with them or go to a store , etc.
Last but not least is get some Scent-Away spray or similar product to spray on your boots and outer garments before leaving to go in the woods. Spray a good layer on your outer garments for sure but they reccomend you spray it on every layer. Also I spray it on my hands and run it through my hair and face too.
Again another alternate cheap way for this is a mixture of baking soda and water in a spray bottle. It works as a scent eliminator and is a lot cheaper.
There may be a few things I forgot, but you get the hint.
