Running groups in a short-term inpatient site, I've gotten a lot of milage out of Marsha Linehan's Skills Training Manual for Treating Borderline Personality Disorder. Intended for clients with Borderline Personality Disorder, many, if not most, of the concepts and worksheets in the DBT manual work with clients with a wide array of diagnoses.
Particularly valuable are the Distress Tolerance Handouts, which offer simple, client-friendly coping skills for crisis situations, some mindfulness-based, some not. One example that lightens the mood: Using "opposite emotion" in a crisis by singing Helen Reddy's "I Am Woman." Hear clients roar.
