All your indexed pages are probably still under your old domain:
Normally it would be a matter of issuing a permanent redirect (301) from the old domain to the new and wait for Google (and everyone else) to update their links. This could well take a lot longer than a few days, so it's a case of being patient. It is important that the redirect stays in place for as long as possible (at least a few months, or forever if you can!).
This is sort of what's happening with your domain, however, there is a slight anomaly:
yannbane.blogspot.com --> yannbane.blogspot.co.uk (302 temporary redirect) ?
yannbane.blogspot.co.uk --> www.yannbane.com (301 permanent redirect)
There are 2 redirects. Why is the first redirect a 302 (temporary redirect) and not a 301? Why is the first redirect even there at all? However, I suspect it will be OK and Google will see that your new (final) domain is the one to be indexed, but I'm not 100% sure - so please comment.
EDIT: As noted in comments, the middle (temporary) redirect would seem to be dependent on the users location (probably returning what it thinks is the nearest). I'm in the UK, hence .co.uk. If you try the tool at web-sniffer.net (based in Germany), it shows a temporary redirect to
yannbane.blogspot.de as the first hop.
