Preheat air fryer to 400°F and lightly grease the basket with a small amount of oil.
Slice the chicken breast into even strips and dip each piece into half of the egg whites.
Whisk together the almond flour, garlic powder, smoked paprika, sea salt, and black pepper in a shallow bowl.
Dredge the chicken strips in the almond flour mixture until fully coated and place them in the air fryer basket.
Air fry the chicken for 12-15 minutes, flipping halfway through, until the coating is golden and the chicken is cooked through.
While the chicken cooks, whisk the oat flour, baking powder, and the remaining egg whites with a splash of water to create a smooth waffle batter.
Pour the batter into a preheated, oiled waffle iron and cook until the waffle is firm and steam stops escaping.
Place the warm waffle on a plate, top with the crispy chicken strips, and finish with a light drizzle of maple syrup.
