I'm not sure if this is what you want, but try adding the following to your
document preamble to see one approach:
\usepackage{blindtext}
\usepackage{graphicx}
\addtolength{\headheight}{10ex}
\lhead{\vfill{}My Heading Text\vfill{}}
\rhead{\includegraphics[height=10ex]{/usr/share/lyx/images/banner}}
I'm using an image that ships with LyX; you may need to change the path in the
last line if you are on Windows or a Mac (or you can just change it to your own
image). I'm setting a height of 10ex for the graphic; if you want to change
that, be sure to make the same change in the \addtolength command. (You must
manually adjust the header height to accommodate the graphic.)
HTH,
Paul
