Using a 3 pt impromptu speaking style of responding can help a lot. Many people ramble and aren't concise which can appear evasive.
Practicing public speaking can make you aware of your verbal tics - uhms ahs or saying "stuff" you use which can make you sound like you don't know what you're talking about.
Aggressively apply to jobs you don't want just for the interview practice. And study "good answers" to common questions on the internet ("strong points ? Weaknesses?" Fluff).
I do a fair amount of public speaking (I've spoken at Lambda Days six times, the Clojure Conj once), and I was a university lecturer, so that stuff isn't too hard for me.
I'm definitely guilty of rambling though; it's pretty hard for me to do say concisely. I'm not 100% sure of the best way to get better at that.
