Preheat your air fryer to 400°F and lightly grease a waffle iron with half of the avocado oil.
Slice the chicken breast into thick strips and toss them in a small bowl with the almond flour, smoked paprika, garlic powder, sea salt, and black pepper until evenly coated.
In a separate bowl, whisk together the oat flour, egg white, Greek yogurt, and baking powder until a smooth batter forms.
Pour the batter into the preheated waffle iron and cook for 4-5 minutes until the exterior is golden and firm.
Place the coated chicken strips into the air fryer basket in a single layer and cook for 10-12 minutes, flipping halfway through, until the crust is crunchy and the chicken is cooked through.
Place the warm waffle on a plate, top with the crispy chicken strips, and finish with a drizzle of pure maple syrup.
