terminated vs lay off (benefits still paid.)

I was layed off from my job due to work cut back. I was a full time contractor in the computer Industry. My company confirmed my lay off with the unemployment office when I filed stating that I was NOT terminated but Layed off. The person that assumed my duties has now been fired. The company is interviewing candidates for my job. Sine I was not terminated, shouldnt I be called back to work before interviewing outside candidates? I understand TEXAS is an at-will state, but I was not terminated, I was layed off and the company is currently paying my health and dental benefits ( not cobra) That in itself should be proof that I am not terminated but in a layoff status. What are the leagal reprocussions to them not returning me to full time contract status before hiring an outsider?
