Pat the chicken wings dry with paper towels.
In a bowl, combine the wings with olive oil, soy sauce, curry powder, turmeric, onion powder, garlic powder, ground coriander, salt, black pepper, and paprika. Toss until evenly coated.
Preheat the broiler to 500°F, following your oven's instructions.
Arrange the wings in a single layer on a broiler-safe pan. Broil for 20–25 minutes, flipping halfway through, until browned and the internal temperature reaches 165°F.
While the wings cook, whisk together the mayonnaise, melted butter, soy sauce, apple cider vinegar, the listed seasonings, and dried parsley to make the curry garlic sauce.
In a separate bowl, whisk together the buttermilk, mayonnaise, ranch seasoning, dill, cilantro, chives, and lemon juice to make the coriander ranch. Refrigerate until ready to serve.
Transfer the cooked wings to a clean bowl and toss with the curry garlic butter sauce until evenly coated.
Serve immediately with chilled coriander ranch.
