Combine soy sauce, honey, hoisin, brown sugar, sriracha, ginger paste, garlic cloves, lime zest, and lime juice in a small saucepan over medium heat. Bring to a low boil, then whisk until the sugar has melted. Allow to cool slightly.
When ready, preheat the broiler to high, then coat a sheet of parchment on a baking sheet with cooking spray. Place the salmon skin side down, then pour or brush the marinade on top of the salmon fillet. Reserve the rest for serving.
Broil the salmon for 6-8 minutes, rotating the pan once halfway through, or until the internal temperature of the fish reaches 120F.
Brush the fillets with remaining marinade, if wanted, then serve immediately with sesame seeds, thinly sliced scallions, fresh cilantro, and lime wedges.
