Answer: Bay trees will not withstand freezing weather, so you are right in overwintering it indoors in a very bright location. I'm afraid they are painfully slow growing, even under the best of conditions. I have found that pruning will encourage new growth so you may want to prune it back a little now that it is summertime and it has had a chance to acclimate to growing outdoors. If you're afraid you'll change the shape by pruning, just do a test prune by clipping back a few inches of one of the branches. Watch for new growth so you'll know how it responds to pruning. You can also cut it back a little when you take it back indoors. Hope this helps! You can repot during the growing season as needed.
