Suppose you want to add "Title field".

You have to add following code on this file i.e. Am/Blog/Block/Adminhtml/Blog/Edit/Tab/Form.php

  $fieldset->addField('title', 'text', array(
      'label'     => Mage::helper('blog')->__('Title'),
      'class'     => 'required-entry',
      'required'  => true,
      'name'      => 'title',
  ));
