Is there a field tpl for body and/or title fields?
Title does not use a template, but is rendered directly in page.tpl.php by default.

Display Suite can be used to override this behavior. Many examples available. Here's one for D8, but the principal is the same in D7: https://www.webwash.net/using-display-suite-drupal-8-how-to-use-display-suite-fields/

You may also find using preprocess hooks in template.php to be useful.

Proprocess hooks give you control over the entire render pipeline, so it's hard to give better guidance without knowing more specifics of your use case.
