If you wrote the text yourself instead of copying it from someplace else, then the text is licensed under the CC-BY-SA license (As noted at the bottom of every page, and on the edit page).

Legally, they're allowed to copy it if they attribute it correctly.

If they do not attribute it correctly, then they are indeed "stealing" it. If the other wiki is a Wikia wiki, then contact Wikia Staff.

You can/should also contact the admin of the other wiki directly yourself, and ask them to either attribute you or remove the content.

You could also just add the attribution/remove the content yourself - but given that they're committing copyright infringement, I do not think that the onus is on you to rectify their offence. You're well within your rights to remove the copied content, but this may cause them to block you - and then Wikia Staff will sort it out.
