Places toasted chile pieces and bay leaf in a medium bowl. Add boiling water, and let stand until softened, about 30 minutes. Drain, and discard liquid and bay leaf.
Add garlic cloves to skillet. Cook over medium, stirring occasionally, until very soft and charred, about 10 minutes. Cool completely, and peel garlic cloves. Combine garlic, drained chiles, vinegar, soy sauce, oregano, thyme, cumin, honey, and 1 teaspoon of the salt in a high-powered blender. Process until smooth, adding 1 tablespoon tap water if necessary.
