To make the glaze, combine honey, soy sauce, pineapple juice, brown sugar, lemon juice, vinegar, olive oil, pepper and garlic powder in a small saucepan over medium heat. Bring to a boil; reduce heat and simmer until slightly thickened, about 10-12 minutes.
Heat vegetable oil in a large skillet over medium high heat.
Season chicken with salt and pepper, to taste.
Working one at a time, dredge chicken in flour, dip into buttermilk, then dredge in flour again, pressing to coat.
Working in batches, add chicken to the skillet, 3 or 4 at a time, and cook until evenly golden and crispy, about 3-4 minutes on each side. Transfer to a paper towel-lined plate.
