Preheat the oven to 425 degrees. Spray a baking sheet with canola oil cooking spray.
Heat the oil in a nonstick skillet over a medium-high heat. Add the scallion, green pepper, and jalapeno and cook until the peppers soften slightly, about 3 minutes. Add the ginger and garlic and cook for one minute more. Set aside to cool slightly.
In a large mixing bowl combine the pepper-scallion mixture with the crab, lime zest, lime juice, cilantro, egg, 1/2 cup of the Panko, 1 tablespoon of the mayonnaise, and the salt.
Put the remaining 1/2 cup Panko on a plate. Form the crab mixture into 8 crab cakes and gently roll each in the Panko and place on the prepared baking sheet. Spray the tops of the crab cakes with the canola oil cooking spray to coat lightly.
Bake the crab cakes until they are golden brown on the bottom, about 10 minutes. Gently turn them over and cook for 10 minutes on the other side. In the meantime, in a small bowl stir together the yogurt with the remaining 2 tablespoons mayonnaise and the chili-garlic sauce.
To serve, top each crab cake with about 1/2 teaspoon of the spicy cream and one cilantro leaf.
