If you are autolatrous, you worship and idolise yourself. It's like being idolatrous, but without the need for accessories. It comes from the Greek auto (oneself) and latria (worship). The noun is, of course, autolatry.
I don't know how useful you'll find the word; but, for myself, I'm wondrously fond of mirrors.
Shakespeare once wrote:
Sin of self-love possesseth all mine eye
And all my soul and all my every part;
And for this sin there is no remedy,
It is so grounded inward in my heart.
Methinks no face so gracious is as mine,
No shape so true, no truth of such account;
And for myself mine own worth do define,
As I all other in all worths surmount.
Which is a sentiment that I can identify with perfectly.
