Where in the bible does it say Satan is father of lies?

I am assuming you mean when Satan deceived Adam and Eve? If so, it was in Genesis. Genesis chapter 3 is often entitled "The fall of man" or something similar, which may be what you're looking for.

But in case this wasn't, throughout The Bible Satan is often referred to as "the deciever", "the liar" and things of that nature.

Answer:

Jesus reveals to us that Satan is the "FATHER OF LIES." He "originated the sin." He was the very first to lie.

"...because there is no Truth in him. When he speaketh a lie, he speaketh of his own: for HE IS A LIAR, andTHE FATHER OF IT." (John 8:44)

(NIV): "...there is no Truth in him. When he lies, he speaks his native language, for he is a liar and the father of lies."
