I feel like I should be teaching them about God, taking them to church but Im lost...

I would have thought maybe pentecostal. It's upbeat, singing etc, but still gets the message across. Anglican services are very traditional, so you may get bored (if that's the right word, no offence to anyone) with it. DH and I are Anglican, I prefer the traditional Anglican services whereas dh prefers pentecostal. Our girls like the environment that comes with pentecostal, so we attend those services moreso these days.
ETA: forgot to say, keep reading the books you've got. We have a couple of books which we read to the girls. Every night, we go through a story from the book titled 'My Good Night Bible' with Nina. She's very interested in learning about God.
