If you really wanna hide lying... maybe the best way is to be prepared for any situations that others would be questioning you regarding the truth of your lie. By knowing and being prepared what others will ask, at least your response will be more natural, as if you are telling the truth. Of course, when you have prepared answers, they tend to be more logical. You have more confidence in them as well. Also, just answer their questions and do not overdo that. Providing more than enough only expresses your panic, more precisely your desperate need to show that 'you are not hiding something'. Be consistent. Similar answers must go out to everyone. Don't take chances. If you really are into this, then you should also try learning about body language so that you can manipulate them to your advantage.
