Very simple, but does anyone know which LaTeX template these lecture notes are done in?

This is quite an easy template to copy, you can start with something like this, and further tune things as you want:
\documentclass[20pt]{extarticle}
\usepackage[left=1in,right=1in]{geometry}
\begin{document}
\raggedright
\section{Markov Chains}
\begin{itemize}
\item The Markov property is common in probability
models because, by assumption, one supposes
that the important variables for the system being
modeled are all included in the state space.

There is no single format for a "scientific paper." It really depends what you're writing. Journal and Conference papers typically have a style mandated by the publisher/organizer.
You could just use the "article" document class with two columns. If you use sections, author, title and abstract (from the drop down menu), you should get something that "looks" like a scientific paper without any need for templates or coding. However, the layout will be more basic than if you try something like was suggested by Reinderien, which is feasible (as Lyx does indeed use TeX).
