Marinate the chicken thighs in buttermilk for at least 1 hour.

In a separate bowl, mix together the flour, paprika, garlic powder, salt, and black pepper.

Dredge the marinated chicken pieces in the flour mixture.

Heat vegetable oil in a frying pan over medium heat and fry the chicken until golden brown and cooked through.

In another bowl, combine the flour, baking powder, baking soda, sugar, milk, egg, melted butter, and vanilla extract to make the waffle batter.

Pour the batter into a waffle maker and cook according to the manufacturer's instructions.

Serve the fried chicken on top of the waffles, drizzled with maple syrup and garnished with chopped parsley.
