I have been in a similar situation. Having done a few interviews, I found the language less than a problem than I had thought. I would practice as many cases as possible in English, your native language and of course in Spanish. The case preparation as such is more important than which language you are practising in.
Some more tipps:
a) Learn the most important business words.
b) You will realise that there some expression you will be using a lot ("May a take a moment to structure my thoughts?" "I would first investigate..." "My recommendation is X for the following three reasons.."). Think how you would say these expressions in Spanish.
c) Don't be afraid to use the English terms in the interview if you can't think of the right Spanish word. With a small apology for your "Spanglish" they don't mind too much in my experience.
d) When preparing for the personal fit part (as improtant as the case!!) think about the most probable questions and about the story you will tell them in your answer. Practice your answers in Spanish (story in indefinido, descriptions etc in imperfecto).
Buena suerte!
