Store template in module

Question

I want to store a template for my content-type in a module. This module provides the content-type (via features). My template "node--my-content-type.html.twig" should be in this module, too. Not in the Themes templates/ folder.

I know there are some related questions yet. I think I got the first step already; Drupal is recognizing my template and is outputing its contents.

In Drupal 7 the approach was made with something like this:

function mymodule_theme($existing, $type, $theme, $path) {
  return array(
  'node__my_content_type_machine_name' => array(
      'render element' => 'elements',
      'template' => 'templates/node--my-content-typee-machine-name',
    )
  );
}

Drupal 8 recognizes the template when I change this a bit.

'template' => 'node--my-content-type-machine-name'

So far so good. But now I am trying to render a field in my template and here I am failing.

{{ content.field_body }} ==> This is doing **nothing**

In my theme´s template-folder this is working fine. Any ideas?

You are missing the base hook definition. See how system_theme() does it for block templates. So, add 'base hook' => 'node' and it should work.
