In the container of a blender or the work bowl of a food processor, place tomatoes, bell pepper, cucumber, onion, ⅓ cup water, lime juice, oil, salt, cumin, coriander, and garlic powder; process, in batches if necessary, until smooth. Strain mixture through a fine-mesh sieve, discarding solids. Taste and adjust seasonings, if necessary. Cover and refrigerate for at least 2 hours.
Stir gazpacho well before serving. Garnish with grape tomatoes and cucumber, if desired.
