Sometimes I do more elaborate prayers, but many times I stick to the simple, traditional: "Bless us, O Lord, and these Thy gifts, which we are about to receive through Thy gracious bounty through Christ Our Lord. Amen." It says everything that needs to be said, and, whenever I visit a Catholic house and it's said, I can join right in with everybody else:D
When I was a kid (non-Catholic household), my mother improvised a prayer that became our standard grace: "Dear Lord, give us thankful hearts for these and all your blessings, we ask for Christ's sake, amen." Eventually, we started adding, "and bless the hands that prepared it." Then for a post-holiday leftovers meal, I, being the wise-acre that I am, added, "and bless the hands that repaired it," and that's been a running family joke ever since.
One thing that is rarely done, and that perhaps should be done more often, is to offer thanks for the senses that will make eating the meal enjoyable.
