Slice chicken into 1-2 inch pieces. Set aside.
In a small bowl, whisk together olive oil, paprika, garlic powder, sea salt, black pepper and chili powder.
Pour half of the seasoning mixture onto the chicken (you will use the other half as you grill). Thoroughly massage the seasoning mixture into the chicken.
Place chicken in a sealed container or ziplock bag and allow it to marinate for about an hour in the refrigerator.
While the chicken is marinating, prepare your sauce. Place all the sauce ingredients into a small bowl (greek yogurt, coconut aminos, apple cider vinegar, honey and hot sauce). Mix well, cover and refrigerate until ready to use.
Once the chicken has marinated, remove from the refrigerator and skewer the chicken. Place 5-6 pieces of chicken onto each skewer.
Preheat the grill to 400 degrees.
Once the grill comes to temperature, place the skewered chicken onto the grill.
Using a pastry brush, brush the chicken with the remaining marinade. If necessary, add a few teaspoons of olive oil to the seasonings to allow it to spread a little easier.
Grill for 6 minutes. After 6 minutes, flip the skewers to the other side, brush marinade over once more and grill for another 6 minutes, or until the chicken reaches an internal temperature of 165 degrees.
Carefully remove the skewers from the grill, place onto your serving platter, and drizzle with bang bang sauce.
