Preheat your oven to 425°F and line a large baking sheet with parchment paper, placing a wire cooling rack on top.
Pat the chicken wings thoroughly dry with paper towels to ensure the skin becomes extra crispy.
In a large mixing bowl, toss the wings with the baking powder, sea salt, black pepper, and garlic powder until every wing is evenly coated.
Arrange the wings in a single layer on the wire rack and bake for 35 to 40 minutes, flipping halfway through, until they are golden brown and crisp.
While the wings are finishing, combine the honey, tamari, sesame oil, and rice vinegar in a small saucepan over low heat.
Simmer the sauce for 3 to 5 minutes until it thickens slightly into a glossy glaze.
Remove the wings from the oven and immediately toss them in a clean bowl with the warm honey-tamari glaze.
Transfer to a plate and garnish with toasted sesame seeds and thinly sliced green onions before serving.
