You need to wrap whatever you want to display in an "if" statement. Start with this:
<{if $xoops_isuser == true}>
and end with this:
<{/if}>
Put whatever html you want in the middle and it will only display when the user os logged on.
Use
<{if $xoops_isuser == false}>
if you want something to display only if the user is not logged in.
I have used this extensively from making custom user menus to having "logged in" icons, to changing headers depending on if you are logged in or not.
