Blogger doesn't offer the Social Media follow or like options when you use one of their basic templates.
The only option remains at the bottom of each post:
You have 2 options for how to do this:
1/ Get a template for your blog, which offers this option.
Blogs like https://www.leftclickrightclick.com/ http://www.socialsongbird.com and http://www.socialguidez.com use a template which have this social media option built in.
To purchase a template, feel free to visit this website:

2/ Create and upload your own icons and add their codes into your blog, like explained on the link below (quite techy):
