If you are curious about religions, I would read up on Joseph Campbell. He has a number of books such as "The Power of Myth", "The Hero with a Thousand Faces", etc. Great reading in comparative mythology/religions. It might give you insight on how humans have created these beliefs over time.
As for satisfying "spirituality" with another religion/belief system, I would recommend you take one minute to think about what you are really searching for. I have learned over time that the feeling some people call "spirituality" is nothing more than the natural feeling of awe, joy, a peak experience, etc. I was indoctrinated to think that those feelings can only be gained by some religion or supernatural belief system.
I assure you, as an atheist living without religion, I still get those feelings. I get them when I look through a telescope, read the latest Scientific American, kiss my girlfriend, watch a great movie or documentary, cook, spend time with friends, help someone, etc.
Before you consider looking for a religion to fill some void, you might want to see if you can fill it with other things. You would be surprised. Just a thought.
