The Varisian Tattoo feat from the Rise of the Runelords Player's Guide grants a +1 caster level in a chose school of magic, and grants a single cantrip usable (Con) times per day as a spell like ability.
Indeed it seams that all the Varisians that I have encountered with this feat only had cantrips that they constantly used, usually utilitarian in nature, (Open/Close,etc.). However, a few had unique low powered versions of 1st level spells that fit into the catagory of cantrip, such as Mage Armor that collapses after one strike. I have one enscribed on one of my ventral neckscales. Its a little isoteric but it takes care of one of my daily annoyances.
As for a second power, I found a minor skill bonus would be apt.
