Hi Paulo,
Welcome back.
As per a similar thread, seek out your local (or preferred) flying club/school. Go along and discuss your wants and needs. Basically, get a medical. Your club/school should then conduct 'training as required' to get you back up to standard for a Licence Proficiency Check. The extent of this is partly at the discretion of the examiner but is usually less comprehensive than the initial skills test.
Now, the hard part. The club/school should then help you with all the correct forms and how to make an application. You will be converting your old, expired' JAR licence in to a Part-FCL EASA licence. The club/school should also help you to understand all the mysterious new words and phrases (such as Part-FCL!). hen you get your licence back, keep flying!
Enjoy
