for lessons, ideas, games, etc there is kidssundayschool. you would need to know some spanish to be able to read it. some of the lessons they have in both english and spanish. Though obviously written by a native spanish speaker, I have found grammatical errors with their materials as well, but it is all understandable.
Here is one I found with preschool lessons, crafts, etc. some lessons are free
Child Evangelism Fellowship (CEF)
is always translating their materials, making it possible to get a copy in english and in spanish.
you can go to the site and put 'spanish' in the search area.
one more resource for now:
these are some real classics! CDs of songs like (Let's go to the church, and Don't Monkey with the Devil, etc.) They also have a book of spanish puppet scrips
If you go to the Cokesbury website at www.cokesbury.com you'll see on the menu bar Curriculum, roll your mouse over it and a drop-down list will come up and under Other Languages you will see Spanish - for all their Spanish resources. There you will find material for both children and adults. Hope this helps some.

Here is God's Story: Easter in Spanish:
"La Pascua de Resurrección es una parte muy importante del plan de salvación de Papá Dios. Es una de las partes más emocionante de la historia de Dios y nos enseña cuánto Jesús nos ama. De hecho, puedes ver esto varias veces en la Biblia. A continuación dos lugares donde puedes leer la historia: Marcos 14-16 y Juan 13-21.
