Egg free baking- help!

We're all going to my in laws on Sat for my fiancé's birthday buffet. As always I'll be doing all the baking. His brother's new girlfriend has an egg allergy. I won't be messing with my man's bday cake, as is his favourite, but I planned to make cupcakes for kids anyway. So now I want to make eggless ones do she can eat some. Also it'll be her first time meeting all the family so I want to get it right. All tips or good recipes welcome. Thanks ladies.
