House of Warf

First of all, your name is your name. It is entirely what you want it to be, regardless of whether or not it fits into the pronunciation scheme of any language. That being said...

Marc Okrand has given a canon spelling to "Worf" : {wo'rIv}

Using that as a model, you could try either of the following:
{wa'rIv}
{warIv}

In the first one, the stress is on the first syllable. In the second, it's on the second.

Between these two, I lean toward the second option.
The first might easily taken as {wa' rIv} "one {rIv}". As of this writing, we haven't been given a {Hol} word {rIv}, but we could be one day, and you may not like the implications in its meaning. (We still do not have a word for "excrement", for example.)

The second word, due to being a five-letter word, is less likely to be made a canon word, good, bad, or otherwise.

But I wouldn't recommend {warv}. It looks like an incomplete word. Just my opinion, though.
