For some reason or the other (and believe me, there are plenty) sites get kicked out of the search engines. Suppose this happens to you? Then what? On the forum of SearchEngineWatch some valuable advice has been posted in an ongoing thread on being reincluded in Yahoo and Google. Some excerpts.
For Yahoo! :
” To sum up, the form is at:
http://add.yahoo.com/fast/help/us/ysearch/cgi_feedback
and the email address is:
and make sure your site complies with the webmaster guidelines before contacting Yahoo by either method:
http://help.yahoo.com/help/us/ysearch/
Unfortunately, that domain is almost always down these days. But it be up more often in the future.
There’s also this older thread:

For Google :
[...] do a root and branch examination.
Check your robots.txt,
check for any noindex tags,
check the httpd.conf file,
check the .htaccess file.
Someone could have been naughty and put something in one of these that said “hey google, bugger off”
Always best to assume the worst, as it wouldnt be the first time a website was the victim of some dirty tricks, so try and iron those out first.
You might want to check the cache of a few pages here and there on Yahoo or MSN.
Does the cache match that of the page?
Check for hidden divs, text and things like that.
Run the site through a browser like firefox using various useragents,
see if it changes.
Set the useragent to Googlebot, is there anything there for the bot? Maybe it has a noindex message?
[...]
If you are 100% sure that you or the previous seo haven’t done anything that would be likely to raise a big red flag and the site is crystal clean, then drop google an email explaining the situation, maybe they can help.
