Mercedes Lackey's ``Serrated Edge'' series has elves in a more contemporary setting --- ISTR that there's another series which has literally ``Elves in space'' but am blanking on the name.
Steven Brust's Vladimir Taltos / Dragaera novels are a fantasy series w/ a science fiction back-story. Free short story set in that universe here:

There's also Patricia Kennealy's Keltiad series which is Celts in space.
