Try getting on the Great Source website (owned by Houghton Mifflin Harcourt) and look for Write Traits Classroom Kits (copyright 2007).
I've been using Write Traits for years as a great resource for teaching the 6 traits. Vicki Spandel is one of the creators of 6 Traits from years and years ago when she was with the Northwest WRiting Lab.
They do have a 2010 edition of Write Traits, but didn't see the Spanish option offered. The 2007 specifically states Spanish is available and if you scroll down on the page, it's near the bottom of the order options.
