I don't know what the best way is.

That's right, (maybe beamer too?).

Could this be a problem with different paper sizes?  If so, the use of
the standalone class (see below) may fix this.

That should be happening already.

I had been using tikz like this, (note: this may not work and my
intention is not to preclude your ECM):

#+LATEX_HEADER: \usepackage{standalone}
#+LATEX_CLASS: report

#+begin_latex
\begin{figure}[htb]
\centering
\includestandalone[mode=tex,width=5cm]{/home/myles/docs/repo/ve/tex/axisymm}
\caption[1D and axisymmetric model domains]{\label{figure:axisymm}1D model domain and mesh of line elements
(left), and the axisymmetric variant (right) showing the increased
element volumes associated with the line elements.}
\end{figure}
#+end_latex

And then in /home/myles/docs/repo/ve/tex/axisymm.tex :
