Preheat your air fryer to 375°F.
Slice the chicken breast into even strips and submerge them in a bowl with the buttermilk to marinate for 10 minutes.
In a shallow dish, whisk together the whole wheat flour, garlic powder, smoked paprika, sea salt, and black pepper.
Remove chicken from buttermilk, letting excess drip off, then dredge thoroughly in the seasoned flour mixture, pressing to adhere.
In a medium bowl, stir the self-rising flour and Greek yogurt together until a soft dough forms.
Turn the dough onto a lightly floured surface, gently fold it over itself twice, and shape into one thick biscuit.
Place the chicken strips and the biscuit into the air fryer basket, ensuring they are not touching.
Lightly mist the chicken and biscuit with oil spray and air fry for 12 to 14 minutes, flipping the chicken halfway through.
Brush the hot biscuit with melted ghee and serve immediately with the crispy chicken strips.
