Pat chicken wings dry with a paper towel, then place them in a large bowl. In a small bowl mix together the salt, pepper, garlic powder, onion powder, paprika, cayenne pepper, brown sugar, and baking powder. Add the seasonings to the wings and mix thoroughly until combined.
Add charcoal to half of the grill to create a direct and indirect zone. Add smoking wood to the charcoal if desired. Heat the grill to 400°F and add the chicken wings to the indirect side (side without the charcoal).
Cover the grill and cook for 45 minutes to 1 hour until the wings register 165°F.
Uncover the grill and open all vents. Transfer the wings to the direct heat over the charcoals and grill for 2-3 minutes until the skin becomes crispy and blistered.
Brush the wings with your favorite bbq sauce or hot sauce and then place them on the indirect side of the grill. Let sit for 5 minutes to allow the sauce to thicken on the wings. Remove from the grill and enjoy!
