You should use the same layout, blocks and templates as for
<label>Customer My Account Order History</label>
<block type="sales/order_history" name="sales.order.history">
<block type="core/text_list" name="sales.order.history.info" as="info" translate="label">
<label>Order History Info</label>
<block type="customer/account_dashboard" name="customer.account.link.back" template="customer/account/link/back.phtml"/>
In your case the tag
</sales_order_history> should be replaced with your controller and action names. The user achieving them, when following the appropriate link. Then, you can study what blocks you want to change and how to replace them by your own, while inheriting the appropriate Magento blocks. Perhaps, for your needs will be enough to add your own templates for these blocks without changing them. Anywise, the less you change – the better it works. All changes have to be applied in your own module, and directives should be added to its layout.
