Dry the chicken wings with paper towels.
Mix honey, soy sauce, rice vinegar, vanilla bean seeds (or extract), ginger, garlic powder, and black pepper in a small pot.
Heat the pot over medium heat and cook for 5-7 minutes, stirring occasionally, until the glaze thickens. Remove vanilla bean pod if used.
In a large bowl, mix chicken wings with vegetable oil.
For baking: Heat oven to 400°F (200°C). Bake wings on a parchment-lined baking sheet for 25-30 minutes, flipping halfway, until cooked and golden brown.
For air frying: Heat air fryer to 400°F (200°C). Air fry wings in batches for 15-20 minutes, flipping halfway, until cooked and crispy.
Put cooked wings in a large bowl.
Pour vanilla bean glaze over hot wings and mix well.
Top with sesame seeds and chopped green onions, if desired.
Serve immediately.
