How do you determine whether a lewis structure is depicting an ionic or covalent bond?

When a Lewis structure is depicting an ionic bond, the final result will show the relative charges of each atom based on whether it has gained or lost an electron. So there will either be a (+) or (-) sign next to the atom. While in covalent bonds, there are no charges (usually, but there could be partial charges I think) and the Lewis structure shows lines to depict the number of electrons being shared between the atoms.

There are examples made easy on this site: http://www.kentchemistry.com/links/bond ... isDots.htm
It mainly focuses on ionic bonds so maybe it can help you identify them.

Usually, ionic bonds are between metals and non-metals, whereas covalent bonds are between non-metals and other non-metals.

Patience is right. Covalent bonds don't involve metals, while ionic bonds include one non-metal and a metal.

Covalent bonds form molecules and ionic bonds form ionic compounds.

Ions are anything that have a net electric charge, which is why saying that ionic compounds are only made of metals and nonmetals is dangerous. For example, NH4+ and CO32- are both ions that can form an ionic bond with each other, but neither has a metal.
