Plato is pretty good. He does this cool thing where the theology and morality of the city state is presented in a way which enables further development of the sciences and arts.

Really blows your mind when you start to put it all together.

I just picked up You are Gods and it's actually pretty dense stuff and would be a poor choice if you were tired of Christian thought (even if he winds Vedanta into it). It might be worth having a look at Bentley Hart on Wikipedia and seeing if some of his other work appeals. "The Experience of God" is very good, as is "The Beauty of the Infinite". But obviously he's writing from a Christian perspective. From a completely different tack, you might read the "Tripura Rahasya", that's a good Eastern book of mystical philosophy.

Some of the stuff I found most satisfying was proper modern Christian Apologetics, such as the Handbook of Catholic Apologetics. But the Eastern writing is excellent getting across the scale of the infinite and relating that to people on a personal level.
