You do need castsequence, though, as Light of Dawn has a GCD and you can't put two /cast in one macro if the first spells aren't of GCD.
But the following should work I guess:
#showtooltip
/targetenemy
/castsequence [@target] reset=12 Light of Dawn, Holy Prism;
It makes sure you have an enemy targeted and I think Light of Dawn should have no problem with the [@target] condition. If it has, try it without it - it shouldn't make any difference. If you have an enemy targeted anyway you could just skip the 2nd line.
EDIT: You have to press the button 2 times of course. /castsequence dosen't do that for you. In fact no ingame option will do that. If you'd use an external tool like a keyboard macro, that'd be another thing of course.
