You could do something like this:

PHP Code:

<?php if (nm_is_single()) { ?>
<script type="application/ld+json">
   {
     "@context": "http://schema.org",
     "@type": "PublicationIssue",
     // "name": "My Blog",
     // "ispartof": "...",
     // "mainEntity": "...",
     "headline": "<?php nm_post_title(); ?>",
     "description": "<?php nm_post_excerpt(150, '...'); ?>",
     // "image": "...",
     // "editor": "...",
     // "accountablePerson": "...",
     "dateCreated": "<?php nm_post_date('%Y-%m-%d'); ?>",
     "datepublished": "<?php nm_post_date('%Y-%m-%d'); ?>",
     "dateModified": "<?php nm_post_date('%Y-%m-%d'); ?>",
     "copyrightHolder":{
             "@type": "Person",
             "name": "me"},
     "author":{
             "@type": "Person",
              "name": "me"},
     "url": "<?php nm_post_url(); ?>"
   }
   </script>
<?php } ?>

- Note that the post author is not inserted - currently NM has no template tag for this.
- Also note that the dateModified field contains the post date, not the lastmod date (same reason)
