Cut tempeh into 24 equal strips.
Add ½ cup buffalo sauce, garlic powder, chili powder & pepper to a bowl. Stir to combine. Add the tempeh strips to the bowl and gently stir to combine until coated evenly. Place in the fridge to marinate for 30 minutes.
When you are ready to cook them, add panko breadcrumbs to a bowl. Working 3 strips at a time, add them to the panko and coat on both sides. Place coated strips on a plate. Repeat until all of the strips are coated. Reserve the remaining marinade in the bowl.
Spray air fryer basket with non-stick spray (optional) and place strips in a single layer - you may need to work in batches. Cook at 330 degrees for 12-15 minutes.
Once all of the strips are cooked, add the remaining ¼ cup of buffalo sauce* to the leftover marinade. Add cooked strips to the bowl and toss until coated with sauce. Serve immediately.**
