Slice the chicken breast into thick strips and place them in a small bowl with the buttermilk to marinate for 10 minutes.
In a separate shallow dish, whisk together the almond flour, smoked paprika, garlic powder, sea salt, and black pepper.
Remove each chicken strip from the buttermilk, letting the excess drip off, and dredge thoroughly in the seasoned almond flour mixture.
Mist the chicken strips with avocado oil and place them in the air fryer basket at 400°F for 12 minutes, flipping halfway through until golden and crispy.
While the chicken cooks, whisk the oat flour, egg, almond milk, and baking powder in a bowl until a smooth waffle batter forms.
Pour the batter into a preheated, lightly greased waffle iron and cook until the steam stops and the waffle is firm and lightly browned.
Place the hot waffle on a plate, top with the crispy chicken strips, and finish with a drizzle of maple syrup.
