Prepare the wings: Combine the hot sauce, Cajun seasoning, cayenne and garlic powder in a large bowl and mix well. Add the wings and toss. Cover and refrigerate 24 hours.

Heat about 2 inches of oil in a deep fryer or deep-sided pot until a deep-fry thermometer registers 350 degrees F. Remove the wings from the marinade and drain off excess moisture. Carefully add the wings to the hot oil in batches (the oil may splatter) and cook until crisp, about 10 minutes.

Make the sauces: Whisk the butter and hot sauce in a bowl. Mix the chili sauce and soy sauce in another bowl. Serve with the wings.
