You will need to modify the Navigation block.

Copy code/core/Catalog/Block/Navigation.php

to

code/local/Catalog/Block/Navigation.php

modify this method: _renderCategoryMenuItemHtml() to suite your needs. You will need to check if the category has children and change the HTML markup depending on that.

This will however, change for both top and left hand navigation. If you want to change just the left hand navigation you can do this:

a) rename code/local/Catalog/Block/Navigation.php to something else (also change the class name inside the file to Mage_Catalog_Block_Navigationleft), for example

code/local/Catalog/Block/Navigationleft.php

b) Change the XML config to use our new block for the left hand nav:

<reference name="left">
    <block type="catalog/navigationleft" name="catalog.leftnav" after="currency" 
        template="catalog/navigation/left.phtml"/>
</reference>

Magento will then continue to use the original Navigation block for the top nav :-)
