Welcome Bogalu,
I enjoy a hooka myself on occasion. (that occasion being when my friend who owns one brings his over.) Be forwarned though. Just like people are not going to get the burnt paper and chemical taste they are used to from cigarettes from an e-cig, you are not going to get the smoldering charcoal taste either. But I am sure you are going to enjoy e-cigs. You can get tons of different flavors like you hooka tobacco, and also vanilla, rum or berr flavors if you are the type to flavor your hooka water. This vendor even has a hooka series of juice.
2.1 - Hookah Flavor Series : StrictlyEjuice.com, Flavor Shop! I haven't tried them myself, so I can't say for sure, but they are worth a look.
As a hooka smoker, you are used to smoke practically coming out of your ears. Most of the smaller e-cigs won't be enough for you. Even my penstyle leaves me wanting more at times. I would suggest saving yourself the frustration of trial and error, and just start with a heavy duty mod. There are many people here that will tell you all about them.
An e-cigar or a pipe might do it for you, too. If you do a search for hooka, I believe you will find some people who have made thier own e-hookas. Or maybe you can be the first!
Be well,
~A
