A decent commercial rub is McCormick's Sweet n Smoky. Should be available just about anywhere.
Here's my homemade version of the same rub. Kind of a go-to for me for chicken and pork.
Sweet and Smoky Rub
1/4 cup kosher salt
1/4 cup firmly packed dark brown sugar
2 Tbs plus 2 tsp. smoked paprika
2 Tbs granulated sugar
2 tsp garlic powder
2 tsp onion powder
2 tsp freshly ground pepper
2 tsp chili powder
1 tsp ground cumin
1 tsp ground cinnamon
1 tsp ground ginger
1. Stir all ingredients together and store in an airtight container.
As far as wood, pecan and hickory should be fine. Cherry and hickory works nicely too, my go-to woods for chicken.
