In the DB the flex field is stored as an array of layout names.

$flex_field_name = 'name of your flex field here';
$layout_name = "name of your layout here";
$args = array(
  'post_type' => 'page',
  'posts_per_page' => -1,
  'meta_query' => array(
    array(
      'key' => flex_field_name,
      'value' => '"'.$layout_name.'"'
      'compare' => 'LIKE'
    )
  }
);
