Preheat your air fryer to 400°F and lightly coat the basket with the avocado oil.
Slice the chicken breast into thick strips and place them in a small bowl with the buttermilk to coat.
In a separate shallow dish, whisk together the almond flour, smoked paprika, garlic powder, sea salt, and black pepper.
Dredge each buttermilk-soaked chicken strip into the almond flour mixture, pressing firmly to ensure a thick, even coating on all sides.
Arrange the chicken in a single layer in the air fryer basket and cook for 10-12 minutes, flipping halfway through, until the exterior is golden and crispy.
While the chicken finishes, toast the whole-grain waffle until it is warm and slightly firm.
Place the crispy chicken strips atop the toasted waffle and finish the dish with a drizzle of maple syrup.
