Knowing the subject matter beforehand and linking it to the proper resources.  Also, gaining an understanding of your students learning styles are a basic necessity. 

Reply to Yvette Prior's post: good point Yvette, the studies provide a nice tie-in to the subject matter. The studies put the skills into perspective. 

People skills and work behaviors have many areas that give the definition of soft skills. This has brought so much awareness to me, that it has made me realize some of my strengths and some of my weaknesses as an instructor overall.

I use jeopardy for class involvemnt and particiaption - gets extremely competivie and students pumped up.
