Chapter 12 in the common 'Introduction to Electrodynamics' by David J. Griffiths is about electrodynamics and special relativity. I saw an example in the book about a moving point charge so that seems promising.
I had a book in a course once written by Wolfgang Rindler called 'Introduction to Special Relativity' which had a quite long section about electromagnetism and special relativity, but this book was more leaned towards special relativity than electrodynamics (as you can guess by the title).
How much of special relativity theory do you want? And what is it more specific that you're looking for? How the fields of a point charge transform under the Lorentz transformation? Cause that shouldn't be so hard to find, I guess there is a lot on Wikipedia for example.
For straight, no acceleration then I think that Griffiths may have that (I don't have it on hand to check though). If you want a detailed analysis for more abstract situations (relativistic, accelerating) Jackson has a good treatment of the subject.
