I thought my "World Religions" class at a local community college was one of the best classes I ever took. You might start with that.
Otherwise, I would just pick a different church each week, attend, and see if you like it. If you do, go exclusively for a while to get a better feel for it. If, after a few services, you decide it's not for you, try a new place. Eventually, you should find one that suits your needs.
You could also ask your practicing friends and join them.
My best friend did this and found a wonderful new church. But, don't be surprised if you look everything over and go back to what you grew up with. There's a certain amount of comfort in sharing with your kids what you learned as a kid. I do know that many of the Catholic churches in my area offer a daily, early morning mass or a Saturday evening mass.
Good luck!
