How about talk to the MIL in private, and ask her something like, "would you mind terribly respecting my lack of belief when we're in public as I'm respectful of your belief when we're in private?" And then maybe talk to her about it making you uncomfortable. Use lots of "I"s instead of "you"s too.
A good friend of mine has parents who like to say grace at every meal, even in public, and I basically did the above. They barely even flinched and never suggested I pray with them again. Our relationship actually changed for the better a little.
