If you want to design an "Old Blogger" Template from scratch, you can build on this:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html lang="en">
<head>
<title><$BlogPageTitle$></title>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
<style type="text/css">
#wrapper {margin: 0px; padding: 0px;}
</style>
</head>
<body>
<div id="wrapper">
<h1><a href="<$BlogURL$>"><$BlogTitle$></a></h1>
<MainPage><h2>Latest posts</h2></MainPage>
<ItemPage><h2>Specific post</h2></ItemPage>
<ArchivePage><h2>Archived posts</h2></ArchivePage>
<Blogger>
<BlogDateHeader><h3><$BlogDateHeaderDate$></h3></BlogDateHeader>
<BlogItemTitle><h4><a href="<$BlogItemPermalinkURL$>"><$BlogItemTitle$></a></h4></BlogItemTitle>
<$BlogItemBody$>
</Blogger>
<h2>Archives</h2>
<BloggerArchives><h3><a href="<$BlogArchiveURL$>"><$BlogArchiveName$></a></h3></BloggerArchives>
<h2>Powered by</h2>
<h3><a href="http://www.blogger.com/">Blogger</a></h3>
</div>
</body>
