Rack, i don't know about a smoker because i don't have one but here's a good grilling recipe that i use that is very tasty that might work just as good on a smoker.

1 bottle Kraft Zesty Italian Sauce
1 pkg Lipton Beef Onion Soup Mix

Just pour the sauce and soup mix in some type of tupperware bowl and slice some deer meat (preferably backstraps) and put in the bowl with the ingredients. Take a spoon and stir it all around until the meat is covered good and then seal the bowl and put in the fridge for a couple of hours to marinate. Slap them babies on the grill or smoker and cook'em up. Be careful not to overcook the meat. I'm sure you'll like the taste.
