Preheat your air fryer to 400°F and a waffle iron to medium-high heat.
Slice the chicken breast into even strips.
In a small bowl, whisk half of the egg; in another bowl, combine the almond flour, arrowroot powder, garlic powder, onion powder, paprika, sea salt, and black pepper.
Dip each chicken strip into the whisked egg, then coat thoroughly in the seasoned flour mixture.
Lightly mist the coated chicken with avocado oil and air fry for 10-12 minutes, flipping halfway, until the exterior is golden and crisp.
While the chicken is air-frying, whisk the remaining half of the egg with the oat flour, Greek yogurt, and baking powder until a smooth batter forms.
Pour the batter into the preheated waffle iron and cook until the steam stops and the waffle is firm and fluffy.
Place the waffle on a plate, top with the golden chicken strips, and finish with a drizzle of pure maple syrup.
